Resource in cluster service requires IP address to be available first, but ip resource seems to start after the resource in RHEL 5 or 6

Issue

We need the IP address to be available before our script starts, but the cluster service starts the script first.
ip resources should be started before script resources. The ip resources however come up after the script resources.

Red Hat Enterprise Linux (RHEL) 5 or 6 with the High Availability Add On
One or more cluster services in /etc/cluster/cluster.conf with an ip resource and another resource configured as "siblings", for instance:

<service ...>
   <ip .../>
   <lvm ...>
        <fs ...>
            <script .../>
        </fs>
   </lvm>
</service>
